The core wrapper 1 providing lateral protection of yarn packages projections from the yarn body serve to protect the yarn 2, the said packages comprising a body of wound yarn winding shoulders from abrasion by supporting surfaces. 3 disposed on a core 4 which core projects above and below the shoulder of the yarn body. As shown in the The protection of the yarn winding shoulders is very important since, while an abraded yarn along the yarn winding edge can be removed by stripping off a relatively short length of yarn before the yarn package is mounted for twisting, weaving or the like, a defect in the yarn which appears along the shoulder cannot be so removed. Since the slightest defect in the yarn creates a visible defect in the finished fabric, the trade rejects yarn packages in which shoulder defects are detected. For this reason it is essential that both the upper and lower yarn winding shoulder be protected from rubbing, snagging and the like at all times.

The yarn as it is shipped from the manufacturer is usually very fragile, due to fine denier, lack of twist, absence of size and the like. In view of its fragile nature, special precautions must be taken to avoid injury to the yarn while it is being unwound. Since the package is designed for over end take oif, any possible point of abrasion must be avoided along the package edge. For this reason, knots which may occur to join ends of yarn are laid across the upper yarn winding shoulder where they are plainly visible and where they will not rub yarn removed ahead of them. Care must also be taken to avoid nicks, abrasions and the like to the outer surface of the upper core projection against which the yarn relatively near the core drags on take-ofi. It is therefore important that contact of any packaging with this surface be avoided to prevent the surface from being scuffed.

An object of the present invention is to provide a novel and useful package for protection of round tubes of yarn and the like during transportation.

Another object is to provide a novel and useful combination comprising an outer wrapper and position locking means for a tube of textile yarn or the like wherein the yarn, during transport, is supported solely by its core.

These and other objects will become apparent in the following description and claims.

The invention will be more readily understood by reference to the drawings.

Figure I is a perspective view of an embodiment of the combination of the present invention.

Figure H is a blank having a resilient fitting foldable into a V-shape and of such dimensions to be capable of insertion within the core projection of a wound tube of yarn.

Figure III is a fragmentary view of a pad containing figure, tiers of yarn packages are disposed between separating pads 5 from which a V-shaped fitting 6 protrudes to grip the inner periphery of core 4, the said fitting preventing lateral displacement of the said yarn package.

Figure I'I illustrates a blank foldable into fitting 6. As can be seen from the drawing, this blank is essentially two rectangular and similarly shaped members having beveled corners 7, symmetrically disposed on prescored line 8 for folding, a keying slot 9 along the edge of each of the rectangular members opposite the prescored line and a ledge forming recess 10 parallel to and symmetrical with prescored line 8 extending from the outer edge of the blank through the depth of keying slot 9, thereby forming a ledge 11 when the rectangular members are folded along line 8 until the edges of recess 10 are in mutual contact.

Figures III and IV are fragmentary views of separating pads 5 illustrating two embodiments of the V-shaped receiving aperture 12. V-shaped fitting 6 (Figure II) is loaded into receiving aperture 12 by folding the fitting along prescored line 8 until the edges of recess 10 are in mutual contact as described above, placing the lower edge (i.e., that edge at which recess 10 terminates) into receiving aperture 12, bending within their elastic limits those edges of fittings 6 opposite to prescored line 8 to permit their passage within loading slots 13 which are located at the extremity of each arm of receiving aperture 12 adjacent to, and at a slight angle to the edge of the said V. When fitting 6 has been inserted to that depth wherein keying slot 9 is opposite separating pad 5 the edges are released and fitting 6 is secured from withdrawal and insertion motion at each extremity of the V of receiving aperture 12 as Well as secured from further insertion motion at its apex. As will be seen by a comparison of receiving aperture 12 in Figures III and IV loading slot 13 may angle toward or away from the acute angle formed upon folding fitting 6 into its V shape. When fitting 6 is disposed and locked in receiving aperture 12 it projects from each surface of pad 5 in the form of a V upon which the cores of wound yarn bodies may be slideably mounted by insertion of the said fitting within the saidcore.

Figure V is another embodiment showing the blank of a fitting suitable for mounting cores of different diameters on opposite surfaces of a separating pad. in this embodiment a keying slot 9 is provided both at the edges opposite the-prescored line and along the edges of recess 10 immediately below ledge 11.

Figure VI is a side view of the fitting-6 shown in Figure V disposed in a separating pad 5, the fitting having mounted on opposite surfaces of padfs yarn-bodies 3-'mounted on' cores 4 of difierent diameter. As shown m the illustration, it is notf essential thatthe-edgesof recess 10 be in mutual contact' when 'fittingsdis lo'eked in its aperture.

Figure-"VIIis another embodiment of ai-suitable fitting wherein a triangular web" 14 is disposed between each of the symmetrical I rectangular members which members have beveled corners -7, the rectangular members being disposed along the edges of 'trian'gular -web '14 --at prescored lines 8 so that when 'foldedalongth'e lines tothe extent of mutual contact-of the edges of recess ltl a V-shaped'fitting is formed suitable --for insertion as previously described'in receiving aperture 12, the said fitting being locked by keying slots 9 to the separating ;pad. In this embodiment fitting 6 protrudes from only one surface of the separating pad, triangular web 14-lying 'flush againstthe opposite surface of the saidpad.

The resilientfitting-and separating pad are preferably constructed of corrugated board of multi-walled 'construction, although plastic or other low cost materials having similar characteristics of bursting strength, rigidity and density may be utilized. The inserts and pads may be die-cut or fabricated by any conventional "methods. lhe'beveled corners of the resilient fitting are not a necessary feature of the invention although they are preferredsince such construction facilitates insertion of-the fitting in-the pad aperture as well as placement of the yarn-core on the fitting.

The angle of the aperture may vary from about to 'about90", but for optimum rigidity of the supporting insert, is preferably from about 50 to about 70'. In the preferred embodiment, and as shown in the illustrations, the V-shaped apertures of the separating pads are flattened .at their outer apex, thereby increasing the areaof contact between the ledge of-the resilient fitting and the separating pad. The slight angle of: the loading slot from the arms of the receivingaperture may vary from about -2-to about'SO" but'is'preferablyfrom'about 5 *toabout 7 The V-shaped fittings are inexpensively i'fabricated;

easily-installed, and efiic'ient in formingstrong; vertical extension. The structure permits packaging of each yarn body individually, of multiple yarn bodies 'side-by'side or vertically or 'a multiplicity of yarn bodiesmay be packaged in tiers as illustrated. The nature of the outer wrapperis not cn'tical and may be cloth, plastic 'orthe like.

'Whilethe invention has been particularly illustrated by reference to yarn bodies wound-on cylindrical cores,

paper, cardboard,

the combination of resilient fittings'locked in separating pads may be employed to anchor other-types ofstructures such as yarn bodies mounted on cones, yarn bodies mounted on spools, bodies of ribbon tape and sheet materials mounted on hollow core structures and the like.

Many other modifications will be apparent to those skilled in the art fromta reading of the above without a departure from the inventive concept.
